A uniform stick 1.3 m long with a total mass of 270 g is pivoted at its center. A 3.8-g bullet is shot through the stick midway between the pivot and one end. The bullet approaches at 250 m/s and leaves at 140 m/s. With what angular speed is the stick spinning after the collision?

A thin 1.5-m-long uniform rod with a total mass of 1650 g is suspended vertically at the upper end. The moment of inertia of the rod in respect to the center of mass is mL2/12 (where L is the total length of the rod). A 12-g bullet is shot to the lower end of the rod and embeds there. The bullet speed before impact is 380 m/s. Calculate the amount of energy transferred to the heat during the collision.

A uniform disk with mass 8.5 kg and radius 8 m is pivoted at its center...

A uniform disk with mass 8.5 kg and radius 8 m is pivoted at its center about a horizontal, frictionless axle that is stationary. The disk is initially at rest, and then a constant force 31.5N is applied to the rim of the disk. The force direction makes an angle of 35 degrees with the tangent to the rim. What is the magnitude v of the tangential velocity of a point on the rim of the disk after the disk...

A thin, uniform disk with mass M and radius R is pivoted about a fixed point...

A thin, uniform disk with mass M and radius R is pivoted about a fixed point a distance x from the center of mass. The disk rotates around the fixed point, with the axis of rotation perpendicular to the plane of the disk. What is the period as a function of x, M, R, and acceleration due to gravity (g), and what is the distance x that gives the smallest period?

A uniform stick, mass m and length l, is placed in a horizontal plane by hanging...

A uniform stick, mass m and length l, is placed in a horizontal plane by hanging it from a massless string attached to the center. A ball of mass M moving with speed V in the plane of the stick. The ball strikes the stick at a distance d from the center. the collision is elastic. Find the resulting translational and rotational speeds of the stick and the resulting speed of the ball. show that the relative speed of the...

Two people are carrying a uniform 3 m long steel beam that has a total mass...

Two people are carrying a uniform 3 m long steel beam that has a total mass of 32.1 kg. One person is supporting it at the far left end with an upward force of 120 N, while the second one is supporting it somewhere near the right end with an unknown force. How much force is required from the second person in order to balance the beam? H ow far from the right end must the second person lift in...

A uniform helicopter rotor blade is 8.97 m long, has a mass of 104 kg, and is attached to the rotor axle by a single bolt. (a) What is the magnitude of the force on the bolt from the axle when the rotor is turning at 329 rev/min? (Hint: For this calculation the blade can be considered to be a point mass at its center of mass. Why?) (b) Calculate the torque that must be applied to the rotor to...
